Current (2025) installation costs across the Fraser Valley, Lower Mainland, and Southern BC vary significantly based on system type. Design is a separate professional service, typically ranging from $3,200–$5,200, and is required before any installation can begin. Installation costs break down roughly as follows:
| System Type | Typical Installation Cost | Notes |
|---|---|---|
| Type 1 Gravity | $20,000–$30,000 | Lowest cost; requires excellent native soil — rarely permitted in the Fraser Valley |
| Type 1 Pressure Distribution | $35,000–$45,000 | More common; includes pump chamber, control panel, and electrical |
| Type 1 Sand Mound | $55,000–$65,000 | Very common in the Fraser Valley due to poor soils and shallow water tables |
| Type 2 & 3 Advanced Treatment | Price varies significantly | Required for large homes, small lots, waterfront, or sites with little usable native soil; advanced treatment units can add $15,000–$65,000 to the project |
A useful rule of thumb: a larger home on a smaller lot typically means a more expensive system. A smaller home on a larger lot with good soil drainage is the combination most likely to come in at the lower end.
